form data customization -> how to edit the code?

[fmaltez]

If i wanted that a form data go to a specific table and collums in DB, what files do i need to edit myself?

i notice that for example act_export.php does use and export the data and create a excel file....so i will use some parts of it.

but if i want to see/edit the "form" code, (the frontend engine), where do i start? what files?

_______________________________________________
now:
[FORM]
name, phone, adress
|
BLOB data in phpwcms_formresult / formresult_content
& Email
_______________________________________________
what i want to do:
[FORM]
name, phone, adress
|
text in custom_table / custom_collums (name,phone,adress)
_______________________________________________

what files should i edit/mess around?

thank you

PS: i know/think that Oliver is working on this, so problaby will appear in future versions, but i'm need urgently to do it... sorry
